Auxiliary spring rigidity design method for non-end-contact type few-leaf parabolic type main and auxiliary springs

The invention relates to an auxiliary spring rigidity design method for non-end-contact type few-leaf parabolic type main and auxiliary springs and belongs to the technical field of suspension steel plate springs. Auxiliary spring rigidity can be precisely analyzed and designed according to structural parameters of all main springs of the non-end-contact type few-leaf parabolic type main and auxiliary springs, the length of the auxiliary spring, elasticity modulus and auxiliary spring rigidity design required values of the main and auxiliary springs. It is verified that the auxiliary spring rigidity design method for the non-end-contact type few-leaf parabolic type main and auxiliary springs is correct, and a reliable design method is provided for auxiliary rigidity design of the non-end-contact type few-leaf parabolic type main and auxiliary springs. By means of the method, accurate and reliable auxiliary spring rigidity design values of the non-end-contact type few-leaf parabolic type main and auxiliary springs can be obtained, and accordingly the design level and performance of products and vehicle ride comfort can be improved. Meanwhile, product design and test cost is reduced, and development speed is increased.
